[0024] Example

[0025] In existing technologies, chemical powders are mostly scooped out using a spoon. However, when scooping powder with a spoon, the force applied each time varies, resulting in differences in the amount scooped out each time. This reduces the accuracy of powder scooping and consequently affects experimental results.

[0026] Please see Figures 1-5This utility model provides a technical solution: a device for quantitative dispensing of chemical reagent powder, including a spoon handle 1 for dispensing chemical powder, a hanging hole 2 at one end of the spoon handle 1, a spoon head 3 fixed at the other end of the spoon handle 1, a through groove 4 on the surface of the spoon handle 1, a reset component 5 inside the through groove 4, a rotating structure 6 on the surface of the reset component 5, and a scraping mechanism 7 on the surface of the rotating structure 6 to "smooth out" excess chemical powder and thus achieve quantitative dispensing, the scraping mechanism 7 includes a scraper 701 and a finger sleeve 702, the scraper 701 is disposed on the surface of the rotating structure 6 and the scraper 701 is in contact with the surface of the spoon head 3, the finger sleeve 702 is fixed to the top of one end of the scraper 701, a locking structure 8 is provided on the top surface of the spoon handle 1, and a locking structure 8 is provided on the bottom surface of the spoon handle 1. A latching component 9 is provided. To allow the scraping mechanism 7 to reset after completing the "smoothing" operation, thus facilitating the next round of use, a reset component 5 is provided. The reset component 5 includes a slide rod 501 and a tension spring 502. The slide rod 501 is fixed to the inner wall of the through groove 4, and the tension spring 502 is nested on the surface of the slide rod 501. One end of the tension spring 502 is fixedly connected to the inner wall of the through groove 4, and the other end of the tension spring 502 is fixedly connected to the slider 601. To "smooth" the entire surface area of ​​the spoon head 3, a rotating structure 6 is provided. The rotating structure 6 includes a slider 601 and a pin 602. The slider 601 is slidably sleeved on the surface of the slide rod 501, and the side of the slider 601 is slidably attached to the inner wall of the through groove 4. The pin 602 is fixed at the top center of the slider 601, and the scraper 701 is rotatably sleeved on the surface of the pin 602.

[0027] To prevent the scraper 701 from wobbling and ensure it remains in close contact with the spoon head 3, thus guaranteeing a smoothing effect, the top and bottom surfaces of the scraper 701 are respectively in contact with the pin 602 and the slider 601. The pin 602 has a "T"-shaped structure in its front view. To lock the scraper 701 in the "idle" state and prevent it from wobbling and affecting its handling, a locking structure 8 is provided. The locking structure 8 includes a side plate 801 and a plug 802. The side plate 801 is fixed to the top surface of the spoon handle 1. The insertion rod 802 is fixed to one side of the side plate 801. A insertion hole is provided at the center of one end of the scraper 701. The insertion rod 802 and the scraper 701 form an insertion structure through the insertion hole. In order to facilitate the index finger to operate the spoon handle 1 to move and the thumb to insert into the finger sleeve 702 to drive the scraper 701 to rotate, so as to achieve the purpose of single-handed operation, a latching component 9 is provided. The latching component 9 includes a vertical plate 901 and a horizontal plate 902. The vertical plate 901 is fixed to the bottom of the spoon handle 1, and the horizontal plate 902 is fixed to one side of the bottom of the vertical plate 901.

[0028] The working principle or structural principle is as follows: First, when using this device, the operator needs to grasp the handle 1 of the spoon with their palm, insert their thumb into the finger sleeve 702, and place their index finger on one side of the vertical plate 901. Then, by grasping the device, the operator uses the spoon head 3 to scoop up the chemical powder. When scooping, the amount of powder scooped up needs to be greater than the amount that the spoon head 3 can hold. After that, the operator uses their index finger to pull the vertical plate 901, causing it to move the handle 1, thus creating a "relative displacement" with the scraper 701. This allows the end of the scraper 701 to move to the position of the spoon head 3. Next, the operator uses their thumb to move the finger sleeve 702, causing it to rotate the scraper 701 back and forth, thereby "smoothing" the excess powder on the surface of the spoon head 3. This ensures that the amount of powder remaining inside the spoon head 3 is the same as the amount it can hold. By operating in this way, the purpose of quantitative sampling can be achieved.

[0029] The components such as the tension spring 502 in this device can be maintained periodically. This device is only used for a certain chemical powder. The "quantitative quantity" in this application is within a certain allowable error range and is not an absolute quantitative quantity.

[0030] In summary, this device has the advantages of simple structure and quantitative sampling capability.

In particular, the features described in the various embodiments and / or claims of this utility model can be combined or combined in various ways without departing from the spirit and teachings of this utility model.
